SQLite，是一款轻型的数据库，是遵守ACID的关系型数据库管理系统，它包含在一个相对小的C库中。它是D.RichardHipp建立的公有领域项目。它的设计目标是嵌入式的，而且目前已经在很多嵌入式产品中使用了它，它占用资源非常的低，在嵌入式设备中，可能只需要几百K的内存就够了。它能够支持Windows/Linux/Unix等等主流的操作系统，同时能够跟很多程序语言相结合，比如 Tcl、C#、PHP、Java等，还有ODBC接口，同样比起Mysql、PostgreSQL这两款开源的世界著名数据库管理系统来讲，它的处理速度比他们都快。(SQLite, a lightweight database, is a relational database management system that complied with ACID, which is included in a relatively small C library. It is a public domain project established by D.RichardHipp. Its design goal is embedded, and it has been used in many embedded products. It occupies very low resources. In embedded devices, it may only need hundreds of K of memory. It can support the mainstream Windows/Linux/Unix operating system and so on, and can combine with many programming languages, such as Tcl, C#, PHP, Java, and ODBC interface, as compared to the world famous Mysql database management system, PostgreSQL two of the source, the processing speed is faster than they.)
